sections forming the inner and outer Walls'l of the tire box sectionA of the boiler.

The main object of the invention' is to apply the above construction tov a'sloping Wagon top boiler.

The invention also relates to means for coupling the inner and outer sections to the niu'dring and to further details of construction, which will be fully described hereinafter, reference being had' to the accompanying drawings in which:-

Figure l, is a longitudinal sectional view of the rear end of a locomotive boiler on the ling 1--l, ligLQ; showing the lire box' construction; Fig. 2', is a View taken on the lin-e 22, Fig. l; Fig. 3, isV a transverse sectional view on the line 3 3, Fig. l; Fig. 4, is a detached perspective View ofthe rear 4tube sheet; Fig. 5, is a detached perspective View of the inside door sheet; Figs. 6 and?,

are enlarged plan views showing the method of connecting the sections at the mud drum; Fig. 8, is un enlarged sectional view on the line 8--8, Fig. l; and Fig. 9, is a view of a modification.

Referring to the drawings, A is'the shfll ,of ,the boiler and a are the. flues.

F is the rear tube sheet to which the flues are attached.

G is the inside door sheet and H is the outlside door sheet, both inclined, as shown.

The top of the lire box'section B of the boiler 'slopes toward the rear, as shown; the sections E and D forming respectively the inner and outer shell of the boiler at'the fire box and minted so as to be atright angles to the inclined Wagon top', as' clearly shown in Fig. 1. The stay plates C are also arranged at an angle, as shown. The sections' c of the outside casing E are iliade; channelshaped' and have anges which project outf wardl'y and these flanges are secured by rivets to the stay plates, as' shown. The invie'asih lf), which forms the shell f libe l With the flanges project-ing outwardly and are secured by rivets to the stay plates C. `f rIhus the interior of the tire box B has an even, unobstructed surface, while the flanges and rivets of the inside casing are projected into the Water space and are protected, While the outside flanges project on the outside of the boiler.l

`By setting the sections e and' d at right angles with the inclined line of the top of the fire section of the boiler-,they Will not be at right angles with lthe longitudinal- ,tubes of thev boiler. Therefore, I make. the tiib'e sheet F as clearly shown in Figs. V1 and 4: The portion f tol which the tubes are secured is oii'set in respect to the balance of angles to the line of the tubes. This not only allows for the ready fastening of the tubes to the tube sheet,I but also materially sheet is bent toproject into'the lire box, as shown' at f2, and is secured to the mud ring I, While the body of this tube sheet forms ftlie forward stay sheetand is riveted to the ,to theiirst of the series of channel sections c, as Well as being secnredto the inner secstruction.

'A is shaped as shown in Fig. 1, and is bent at' a2 and secured to the mud ring lf. The two parallel surfaces a and j" are secured together by a coupling' K, illust-rated in F in the formA ofv a socket and the part k" has af and the other is attached to the portion' I Thus the two portions are prevented from spreading, yet are-capable of longitudinal movement.

The channel sections and d, which cornpse' the main portionlof t'he Ere box structure are ,-inllar in" shap'and size until they reach' the end of the boiler and atffthis point a shapedouter section e and a shapedl inner section'd/ are placed, asf shown in Figs. 1 and?, between t-h'efsaidsheet and the outside door s'lieets G' andx H respectively.

the inner and the outer casings al and e.- The outside door sheet l-l is flanged and is coupled to the loose stay sheet, as well as to the web g of the inside door` sheet. The stay bolts are used where necessary and stay rods extend from the outside door sheet I-l; being secured at dilierent points to the outer casing; as shown by dotted lines in diagram, Fig. l.

To simplify and perfect the coupling between the inner and outer sections andthe niudring, l reduce t-he flanges of the sections e of the outer casing E at the'mud ring, as shown in Fig. 6, allowing the edges of thesaid sheets to extend beyond the reduced flanges and l also bevel the sections at n' at each side so as to provide a lf-shaped groove on each side of the projecting portion of the stay sheet C.

l weld the three parts together by any of the ordinary processes, forming a joint, as illustrated in Fig. 7 i The flanges of the inside casing D are entirely cut away and the curved body portion reduced so that it will tit snugly against the mud ring I. Each sect-ion Z is beveled at @T1/m at each side so as to form a V-shaped projecting stay plate C. These parts are also Welded so as to produce a joint, as illustrated in Fig.

7. The plates are secured to thel stay sheet by rivets or ,bolts a', as illustrated in Fig. 1. By this construction, l dispense with all lapping joints at the mud ring and also do away with callring'at this point. All of the rivets pass through solid metal. When it is necessaryto remore any one of the sections e or d, one section can be severed from another section by cutting the welded portion and removing the rivets.

` In' some instances, when it is desirable to extend' the combustionl chamber, a tubular section F2 `may be secured to an annular flange on the tube sheet F and a tube plate F3 secured to the section as in Fig. 9, thus the combustion chamber will extend into the body of the boiler beyond the lire box;

facilitating combustion and providing an extended heating surface. This construction also protects the ends of the flue tubes from the re.

I claim:

1. The combination in a wagon top boiler, of a shell; longitudinal tubes therein; a tube sheet to which said tubes are secured; a series or' inner and outer channel sect-ions and stay sheets connecting said sections, and forming the tire box section; said stay sheets being arranged at an angle to the line of the slope of the inclined top othe lire box section of the boiler,4 the rear tube sheet being arranged on the saine line as the channel section and having the portion to which the tubes are attached otlset so as to be at right angeles with the longitudinal line of the tu s.

nooners 2. The combination of a longitudinal' shell; 'a irebox section having an inclined upper surface; said shell having a section inclined at the rear edge and at right angles to the line of slope of the inclined surface of the lire box section; and a tube sheet located between the shell and the fire box "section having an offset portion to receive portion; tubes therein; a lire box section consisting of an inner and an outer casing; each made of channell sectionsl and connecting stay sheets; said channel sections being arranged at right angles to the inclined line of the upper portionl of the boiler; a rear tube sheetto which the ues are connected forming the front stay'sheet of the boiler; an inside and an outside door section at the rear of the boiler and tapered s0 Aas to be inclined in a reverse direction to the inclination of the flanged sections and so shaped as to be coupled to the stay sections.

'i 4. The combination in a locomotive boiler of the sloping wagon top type, of a body portion having flue tubes therein; a ylire box section having an inner and an outer casing; said casings being made of channel sections and connecting stay sheets; a struck of the tube sheet to which the tubes are at-\ tached being pressed so as to be at right angles to the longitudinal line of the tubes;

while the body portion of the inside andA outside doorsbeets at the rear ot the boiler are inclined in an opposite direction from that of the sections of the casings; and tapered illing sections located between the vinside and the outside door sheets and the rear stay sheet.

5. The combination in a locomotive boiler of the sloping wagon top` type, of a body portion; flue tubes therein; an inner and an outer casing forming the tire box section ofthe boiler; stay sheets connecting the two casings; the rear section of the body having an inclined portion; a mud ring to which the said section is attached; arear tube sheet 'having an inclined portion adapted to the mud ring; with a coupling connecting the two sections so that while they are prevented from separating they" can move longi tudinally independently of each other.

6. The combination o'f a boiler having a, fire box section; a mud ring;"'.a casing formed of a series of sections;l stay' sheets located between the sections; the sections being` beveled at each side; the mud ring and the stay sheets projecting beyond the beveled portion so that upon reducing the projeetinfgportion of the stay sheets by aweld" ing flame, a Welded joint is produced.
